Abstract: The Forest Service, U.S. Department of Agriculture, is developing a process-based model of rainfall-runoff and sediment erosion on disturbed forest sites, principally forest roads and timber harvest areas. The basis of the developing model is the Water Erosion Prediction Project (WEPP) model developed for agriculture and rangelands. The major challenges in adapting this model to mountainous forest conditions are differences in parameter estimation techniques, weather prediction, vegetation effects, and management activities. Simulated and natural rainfall experiments are used for parameter estimations from forest roads and timber harvest areas. Several model components and parameter estimations from field and laboratory experiments are discussed.
